Enzymatic Release

Enzymatic Release

Studying the detailed structural and functional characterization of different types of glycans is essential to understand the mechanism of various biological activities and the pathology of several diseases. CD BioGlyco has been trying to develop simple and effective enzymatic methods to release glycans from complex biological samples. We expect to be your research assistant in the field of glycobiology.


Enzymatic Release

Glycosylation is an important way of post-translational modification of proteins, which has a variety of biological functions, such as immune recognition, signal transduction, cell adhesion, and tumorigenesis. Therefore, the development of effective methods to release glycans from the protein backbone is of great significance to the study of their structure and function.

In contrast to chemical methods of glycan release, enzymatic release can be carried out with minimum instructions in any laboratory. In the past two decades, more and more enzymes including endoglycosidases and glycosidases have been reported to release glycans from glycoproteins under mild conditions. The endoglycosidase endo-β-N-acetylglucosaminidase H (Endo H), peptide-N4-(acetyl-β-glucosaminyl) asparagine amidase F (PNGase F), and PNGase A are the most preferred endoglycosidases, N-glycans can be conveniently and non-selectively released from glycoproteins using these enzymes.

Enzymatic Release Services

Enzymes are useful for the structural analysis of glycans and polysaccharides and for establishing structure-activity relationships in biological systems. To better characterize glycans on proteins, CD BioGlyco has developed an advanced glycan enzymatic release platform. We provide efficient and accurate release services of N-glycan, fucose, galactose, N-acetylgalactosamine (GalNAc), O-glycosylated protein, core-1 O-glycan, and sialic acid for our clients.
